const (
	SharedArtifactsSchema         = "secondbox.release/shared-artifacts/v1"
	SharedArtifactsRecordFileName = "shared-artifacts.json"
)

The architecture-neutral files of a release are built once and published byte for byte by every guest architecture's artifact set. The shared artifacts record binds that directory to one version, tag and source commit.

const GVisorMaterializationSchema = "secondbox.runner/backend-materialization/v1"

GVisorMaterializationSchema is the runner's backend materialization schema.

Functions

func ArchitectureAssetSuffix added in v0.24.0 

func ArchitectureAssetSuffix(guestArchitecture string) string

ArchitectureAssetSuffix qualifies the release files that belong to one guest architecture. A release publishes one artifact set per guest architecture under the same tag: amd64 keeps the unqualified names and shares its architecture-neutral files (SDKs, binaries, OpenAPI, SBOM) with the others.

func ArtifactManifestFileName added in v0.24.0 

func ArtifactManifestFileName(version, guestArchitecture string) string

func ArtifactManifestLocation 

func ArtifactManifestLocation(version, guestArchitecture string) string

func BinaryLocation 

func BinaryLocation(version, name, platform string) string

func CompareVersions added in v0.6.0 

func CompareVersions(left, right string) (int, error)

CompareVersions orders two canonical release versions according to SemVer precedence. It rejects build metadata because release tags do not admit it.

func Digest 

func Digest(data []byte) string

func SharedArtifactFileModes(version string) map[string]fs.FileMode

SharedArtifactFileModes names every shared file of version with the mode it is staged and published with: host binaries are executable, documents are not.
